On September 4, 1569, Cosimo I de’ Medici, the Grand Duke of Tuscany, established the office known as the Senatori del Medici or Senators of the Medici. This development was part of a broader effort to consolidate the Medici family’s power and influence within the newly created Grand Duchy of Tuscany.
